This compact CB transceiver incorporates state-of-the-art microelectronics
into a sophisticated Euro-styled 2-way radio. The superior engineering of
the PRO510XL will treat your ears to professional 2-way radio communications
as you've never heard it before.

"I have been selling these (510 and 520) for over a decade and I can
still say they are one of the best ever made in the small size class.
These radios last a very long time without fail."

The item most
overlooked when ordering a custom radio is the microphone.
Your new tuned radio will NOT sound great with a
stock mic on it If your CB is more than a tool for work,
you NEED to upgrade your microphone. My personal
favorites are the
Astatic 636L and
RD104E.

If you
place an order from outside the continental USA, we will
calculate your actual shipping and send you a PayPal payment
request. We do
NOT export Antennas or Base station radios.
